Rearch On The Monitoring Of GSM-R System Wireless Environment

China's railway industry has made tremendous development since the reform and opening up.Safety is the lifeline of the railway transportation.In recent years,the railway communication industry is also developing quickly.To ensure the stability and security of railway communications,monitoring of railway communications wireless communication environment is becoming more and more important.GSM-R mobile communication system is specialized for railway communications.It is based on the world's most mature and widely used GSM system.It adds some other function to suit for high-speed mobile environment.The relevant department has set up a special band for railway communications to ensure the safety of railway transport.Since GSM-R mobile communication system is finished on the Qinghai-Tibet Railway,more and more GSM-R communication systems are under construction.The security of railway transport draws more and more attention of the country and the people,and it has also become a very important issue.This paper firstly makes an introduction of GSM-R communication system including its background,system architeche and development.Then we know what the GSM-R is and what the GSM-R is built for.Secondly the paper summarizes all kinds of interfaces including the external interface and the internal interface,which affect the normal work of the system.Thirdly the paper introduces some communication quality parameters and designs the methods we can take to mearsue them.Forthly the paper makes an introduction of Technology Solution to GSM-R Monitoring System which is formulated by the State Radio Monitoring Center.After the introduction and research on GSM-R system,we design the GSM-R wireless environmental monitoring system which is based on the methods of mearsuing the communication quality parameters.The monitoring system consists of three parts.They are control center subsystem,monitoring point subsystem and network transmission subsystem.The paper introduces the struct and function of the monitoring system briefly,and then analyzes the design and optimization of the database module detailly.
